Pride Plumbing was called out for a water leak underneath a kitchen sink. Our inspection found that a galvanized drainpipe had deteriorated behind the wall. Based on this, we provided a cost estimate to replace the kitchen sink's under-sink drain assembly, P-trap, and drain line through the floor to under the house in the crawlspace, and to where it ties into the main sewer drain stack, with new PVC piping and fittings.
